One embryo or two to transfer in FET

Hello Dr. Sher,
I am a 49 year old female with two miscarriages behind me. In both cases the embryos were found to be genetically abnormal. My husband and I have two genetically normally (tested) embryos from our younger days we have frozen. Given my age would love to know your thoughts about if you’d recommend transferring one embryo (set) or both (det). There seems to be so much conflicting data out there. Your thoughts would be very much appreciated and welcome.
Thank you for your time
